Abstract: -i-LIGHT COLLECTION APPARATUS FUR A SCANNER             ABSTRACT OF THE DISCLOSURE          In apparatus for scanning a transparent original with a scanning beam relative an optical axis, a tapered optical bar is positioned adjacent the transparent original to collect a diverging beam emerging from the original and, by means of internal reflection, reduce the divergence of the beam relative the optical axis.  The emerging beam is especially diverged when the scanning beam sweeps away from the optical axis or is scattered by an artifact, such as a scratch, on the original.          Particularly in the case of a polychromatic beam emerging from a color transparency, the tapered bar is interposed between the transparency and color dichroic beam separating mirrors to reduce angle shift and polarization color shading due to light rays diverging from the optical axis upon the dichroic interference layers.

Abstract: ABSTRACT OF THE DISCLOSURE     A burner for pulverized, gaseous and/or liquid fuels having an ignition chamber possessing a wall diverging rotationally symmetrically in diameter and an outlet pipe adjoining thereto, according to the present invention comprises an outlet, disposed centrally in the chamber wall, of a pipe for feeding a fuel jet and a twisting air inlet surrounding this outlet for feeding combustion air in twisting motion, which produces inside the ignition chamber a hot recirculation flow.  This hot circulation flow thoroughly mixes the fuel jet and heats it to ignition temperature.          Only a portion of the total combustion air required can be introduced into the ignition chamber as twisting air via the twisting air inlet, and therefore in the region between the chamber wall and the outlet pipe a second air inlet is provided,through which a further combustion air portion, partially or entirely likewise mixing with the fuel jet, can be introduced into the ignition chamber.  The sum of the combustion air portions participating inside the ignition chamber in the mixing with the fuel jet is adjusted to not more than 50% of the total combustion air required.  The burner according to the invention is variable and flexible within very wide limits with respect to fuel type, calorific value of the fuel, and output rates.  The flame of the burner is slender in form with small radial extraction.  The burner will be useful for medium output requirements such as annealing and smelting furnaces, firing kilns for ceramic products and steam boilers.

Abstract: Abstract MOTION SNUBBER Relative axial motion of a pair of strut members is converted into rotation of an escapement mechanism, which in turn oscillates a balance wheel.   If the rotational velocity  exceeds  a  predetermined  minimum,  the  balance wheel  inertia  initiates  a  momentary  motion  snubbing action.    The means used to convert reciprocation of the strut members into rotary motion is releasable so as to permit the operational testing of the motion snubbing mechanism while the strut is mounted in its operational environment.

Abstract: Abstract of the Disclosure This invention relates to a recovery of fatty acids from sewage scum and the subsequent upgrading of the fatty acids as a processed oil.  This upgrading is achieved through vacuum distillation and de-odorization.     This invention relates to a process of recovery, purification and utilization of brown sewage scum or skimmings, which heretofore has been a nuisance waste.   In a first step the scum is run through a heat process and a series of filters.   Entrained water and other foreign solids are removed.  The oily product that solidifies on cooling is found to contain more than 70% of a mixture of fatty acids.   This processed oil, in a crude form, has utility as a wax replacement in fuel logs.   The processed oil can be upgraded by vacuum distillation and is, at the same time, de-odorized.  The foul-smelling low molecular weight compounds are removed in a forerun fraction.  This allows the isolation of a clean main fraction consisting of identifiable fatty acids.

Abstract: ABSTRACT OF THE DISCLOSURE          In a synchronization apparatus in a telecommunication system of the TDM type in which information is transmitted in assigned time slots, in simplex data transmission between a plu-rality of equal transmitter/receiving modules connected to a com-mon bus, the bus is divided into three sections, all transmitters being successively connected to the first section and all receiv-ers being connected to the final section in the same order as the transmitters.  The time delay between the transmitters and the bus is the same for all transmitters and constitutes a fixed value, whereby the total delay on the first section of the bus is determined by the number of transmitters connected.  The same condition applies to the receivers so that the delay on the final section of the bus also is a fixed value.  The intermediate sec-tion of the bus extends from the last connected transmitter to the first connected receiver and is variable in length such that in relation to the size of said fixed time delays it gives a selectable predetermined total time delay between transmitter and receiver in the same module.  Each of the modules contains a local clock oscillator common to the respective transmitter and receiver.  Apart from internal clock signals, the oscillator also sends frame synchronizing pulses for synchronizing remain-ing modules (slave modules) each time the module is selected as the master.  The synchronization pulses are sent once per frame and parallel to the data information from respective transmitter.          With the aid of the apparatus a synchronization is obtained which enables transmission of first data between an artibrarily selected pair of modules and second data between another arbitrarily sel-ected pair of modules using two adjacent time slots without time difference between the sending sequences in the respective time slot.

Abstract: TITLE OF THE INVENTION "APPARATUS FOR PLACING ELONGATE ELECTRICAL INSULATORS ON       THE FLANGES OF RAILWAY RAILS"          ABSTRACT OF THE DISCLOSURE      Beside railway rails there are upward projections which locate the rails and receive parts of clips which hold the rails down by pressing on elongate insulators laid on the flanges of the rails.  The insulators each have two spaced apart projections between which portions of the upward projections lie.     Apparatus for placing the insulators on the flanges of the rails comprises holding means capable of holding by a resilient bias an insulator and means whereby the holding means moves firstly with a component of motion in one direction parallel to the rail and secondly with a component of motion in the opposite direction parallel to the rail and whereby the holding means also descends. Thus the insulator moves with a component of motion in said one direction and one of the projections on the insulator descends and catches on one side of one of the upward projections and the insulator cannot then follow the movement of the holding means, this movement of the holding means causing the holding means to change the angular orientation of the insulator with respect to the holding means which causes a part of the holding means to move against said resilient bias to release the insulator so that it falls into its operative position on the flange of the rail.

Abstract: ABSTRACT      The machine recognition of hand printed characters is performed efficiently and economically by obtaining specific measurements from a normalized form of the hand printed character and using a logic tree and verifier to logically determine the identity of the character.  The measurements found particularly useful are transition measurements which indicate a measure of the black or white run length or number of transitions in a scan line of the normalized character.  To recognize a character, tests are run on the transition measurement by use of the logic tree and verifier.
